This study investigates the relationship between societal complexity and familial complexity. Results suggest that the relationship is somewhat curvilinear; that is, in simpler societies more societal complexity is associated with a larger familial system, but the most developed societies have smaller familial systems. The demographic, economic, and politcal correlates of maximum family size are discussed.

Udy divides methods of work organization into 'production determined', 'technologically determined', 'socially determined', and 'pluralistic' types, and examines their prevalence across societies with varying subsistence activities and levels of social and political stratification. Special attention is paid to processes of integration and differentiation and their role in effecting transitions between organization types.

This study investigates the role of economic development in facilitating political development in preindustrial societies, theorizing that the redistribution of resources is an important factor in this relationship. Results indicate that these two types of development have a curvilinear relationship, and the author concludes that economic development is a necessary but not sufficient cause of political development in preindustrial societies.

This study presents a sociological theory of marriage type based on socioeconomic organization. Results suggest that intensive agriculture, more stratification, greater political integration, a fixed settlement pattern, a larger population, and greater labor specialization tended to be correlates of monogamy.

This chapter examines the variables that are associated with the evil eye belief cross-culturally. Results suggest that the evil eye belief is significantly associated with various socioeconomic and demographic variables. All hypotheses are supported.

This study examines relationships among the instruction of children, household type and size, and political integration. Particular attention is paid to type of instruction--whether the instructor is kin or non-kin, and whether the instruction requires a change in the child's residence. Different types of instruction are theorized to solve problems for children in different household types (e.g. children in mother-child households experience gender identity conflict, and so leave their houses for instruction from non-kin). The causality between instruction and societal complexity is also discussed.

The relationships of aggression and crime to variables of childhood experience, adult behavior, and social structure are cross-culturally analyzed.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

This study investigates the causes of creative florescences in certain time periods in certain societies. Wealth, geographical expansion, democratic support, and external challenge were not significant predictors of creative florescence, but political fragmentation shows a correlation with society’s creativity level.

This study examines how social structure, political organization, and intersocietal relations may affect the incidence of internal warfare (between culturally similar political communities). Results show that in uncentralized political systems, fraternal interest groups and unauthorized raiding parties may increase the incidence of internal war.
